Battery full charge capacity decreased?





As you can probably see from the above image, my battery's full charge capacity has been decreased. Even though I just bought this laptop like 3 months ago, the laptops full charge capacity has been decreased by a huge amount like 5000mWh. I don't know what is causing this I have three questions...

i) What causes a battery to lose its Full Charge Capacity?

ii) Can a full charge capacity be increased (reversed) by using it the right way again?

iii) How can I save my battery from losing it's full charge capacity? Will using it plugged into the charger help it not get decreased?

Repeat the steps Dave suggest you other three times.

Also you can uninstall and reinstall battery from device manager before each charge. You can do that:

1. Press WINDOWS + X

2. Click on "Device Manager"

3. Click on "Battery"

4. Right click on your battery

5. Click on "Uninstall device"

6. Repeat steps 4 and 5 for each element on battery list

7. Click on "Detects Hardware change" (monitor icon)

Sure! I'll do the steps again for 3 times. I'll reply with the result.

Thanks!!
